Application filed March 11, 1889- Serial No. 302,784. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN S. VALLAGE, of Nelsonville, in the county of Athens and State of Ohio, have invented a new and Improved Refuse-Ejector, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved refuse-ejector, which is very simple and durable in construction, ef-

1o fective in operation, and specially designed to remove refuse from ocean steamers, coalmines, mills, caissons, 86C.

The invention consists of a dischargepipe closed at one end and into which proj ects and I 5 opens a steam-pipe carrying superheated steam, a refuse feed-pipe discharging into the said discharge-pipe at the end of the steampipe, and a gas-pipe also opening into the said discharge-pipe between its closed end and the said discharge end of the said refusepipe and steam-pipe The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then 2 5 pointed out in the claims.

Reference is to be had to the accompanying drawing, in which the figure is a side elevation of the improvement with parts in section.

The discharge-pipe A, of suitable diameter, is closed at one end at B, and is provided at its other end with suitable connect-ions or eX- tensions of any desired length. Into the closed end of the discharge or ejecting pipe A extends a superheated-steam pipe 0, having its inner end 0 nozzle-shaped and opening into the said discharge-pipe a suitable distance from the closed end B. The steampipe O is provided with a valve D, and extends into a furnace E, of any approved construction, connecting at its inner end with a coil of pipe F, located above the grate-bars of the said furnace and provided with any desired number of bends. The coil of pipe I connects at its other end with a steam-pipe G, extending to the outside of the furnace E and connecting with the boiler supplying the necessary steam. Avalve ll is formedin the said pipe G outside of the furnace E, and the steam from the boiler passing through the said pipe when the valve H is opened is superheated in the coil of pipe F and passes in a superheated state into and through the pipe C to the discharge-pipe A.

From the furnace E leads the usual chimhey I, provided a short distance from the furnaee E with a branch pipe J, connecting with the disehargepipe A at a point between the inner end of the nozzle O and the closed end B.

Into the discharge-pipe A opens an inclined pipe K, directly above the front end of the nozzle 0, said inclined pipe K connecting at its upper end with a pipe L, extending horizontally and carrying a feed-screw N, fastened 6 on a suitable shaft 0, mounted to turn in suitable bearings in the ends of the said pipe L, and provided on its outer end with a pulley P, connected with a suitable driving mechanism for imparting a rotary motion to the said shaft 0.

Into the pipe L and onto the feed-screw N opens a hopper Q, containing the refuse to be ejected. \Vhen the feedscrew N is rotated, the refuse from the hopper Q is forced into the inclined pipe K, and from the latter into the discharge-pipe A.

The operation is as follows: Vhen the valve II in the pipe G is opened, steam is admitted from the boiler to the coil F in the furnace E, is superheated in the same to the required degree, and then passes through the pipe G into the discharge-pipe A. The velocity of the steam escaping from the nozzle 0 creates a vacuum in the discharge-pipe A between the nozzle end and the closed end B. In consequence of this vacuum a draft is created in the chimney I, so that the smoke and gases from the furnace E are drawn through the branch pipe J into the discharge-pipe A, and the hot gases combine with the superheated steam at the inner end of the nozzle 0. The power and value of the superheated steam is thus increased by the addition of the smoke and gases from the furnace E. The ref- 5 use fed through the inclined pipe K from the hopper Q immediately in front of the nozzle O is acted on by the combined force of the superheated steam and gases, so as to force said refuse through the open end of the pipe A to any desired place to which the said pipe A leads.

It will be seen that the velocity with which the refuse is discharged is governed by the velocity of the escaping superheated steam and gases rushing through the pipe A. It is to be understood that the velocity with which the refuse is ejected depends greatly on the pressure maintained in the boiler and the distance the refuse has to be carried through the pipe A before being deposited.

It is to be further understood that the device can be used for a number of purposes. It is, however, particularly adapted for ejecting refuse to any height and at any desiredangle. At coal-mines, where slack and culm have to be disposed of, it is necessary, in order to save room and prevent the obstruction of land, to pile the slack and culm up as high as possible, and as the pipeAcan be extended vertically to any desired height the slack or culm can be easily ejected through the said pipe in the manner above described.

Ashes from boilers and furnaces can also be piled up to any desired elevation to save room, or carried long distances, reducing the expense to a minimum. Sawdust from mi1l pits, which it requires a great amount of labor and expense to remove, can by the use of this device be taken long -distances and to great heights and discharged at a great saving of expense. In large ocean steamers, where the hoisting of ashes and dirt from the hold and engine-rooms is now a slow and laborious proceeding, the work can be made easy, cheap, and efficient, irrespective of stormy or calm weather.

The device is further adapted to the sinking of caissons, for the ejection of the sand and dirt from the interior of the caisson. It is also adapted for ejecting the dirt and mud from dredging-machines to the banks of a canal or stream.

A variety of refuse can be ejected, such as tan-bark, garbage, sand, (KT/C.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a refuse-ejector, the combination, with a discharge-pipe closed at one end, of a steampipe carrying superheated steam and opening into the said discharge-pipe, a refuse feedpipe held at an angle and discharging into the said discharge-pipe at the nozzle end of the said steam-pipe, and a gas-pipe also opening into the said discharge-pipe between its closed end and the said inner end of the said refuse feed-pipe, substantially as shown and described.
